another  formula  Borlinette  recommends  equal  parts  picric  acid  and 
chlorate  of  potassium.  This  is  cheaper  than  the  first,  but  it  is  more 
dangerous  and  must  be  used  with  care. — Rundschau,  Prag,  1888,  p.  91. 
To  file  glass  vessels. — Borntraeger  in  Rep.  anal.  Chem.,  recommends 
to  first  lay  the  file  in  a  strong  soda  lye  and  while  vet  wet  to  dip  it  in- 
to coarse  sand.  A  file  treated  in  this  way  can  be  used  for  filing  glass 
ware,  without  the  least  danger  of  cracking  it. — Rundschau,  Prag, 
1888,  p.  91. 
Liquid  glue,  possessing  great  resisting  power,  and  particularly  re- 
commended for  wood  and  iron,  is  prepared  according  to  Hesz  as  fol- 
lows:  Clear  gelatin,  100  parts ;  cabinet-maker's  glue,  100  parts  ;  alco- 
hol, 25  parts,  and  alum,  2  parts ;  the  whole  mixed  with  a  20  per  cent, 
acetic  acid,  and  heated  on  a  water-bath  for  six  hours.  An  ordinary 
liquid  glue,  also  well  adapted  for  wood  and  iron,  is  made  by  boiling 
together  for  several  hours  100  parts  glue,  260  parts  water,  and  16 
parts  of  nitric  acid. — Rundschau,  Prag,  1888,  p.  74. 
Iodine  Pastilles,  for  disinfecting  the  sick  room,  are  prepared  by  in- 
corporating iodine  and  salicylic  acid  with  paraffin  or  wax,  or  similar 
material.  In  burning  the  pastilles,  the  salicylic  acid  is  converted  into 
phenol,  and  this  is  volatilized  with  the  iodine. — Rundschau,  1888,  p.  50. 
A  general  antidote  for  poisons  is  a  mixture  composed  of  equal  parts 
of  calcined  magnesia,  wood  charcoal,  and  hydrated  oxide  of  iron,  with 
a  sufficient  quantity  of  water.  It  is,  as  a  harmless  and  simple  remedy, 
applicable  in  such  cases  when  the  nature  of  the  poison  is  unknown. — 
Rundschau,  1888,  p.  15. 
As  an  antidote  for  iodoform,  Behring  recommends  a  20  per  cent,  so- 
lution of  bicarbonate  of  sodium. — Rundschau,  1888,  p.  15. 
Corrosive  sublimate  in  external  applications. — Recently  in  a  report 
before  the  Medical  Society  of  Berlin,  Professor  Virchow  called  atten- 
tion to  several  cases  of  corrosive  sublimate  poisoning ;  he  had  already 
in  November  reported  several  cases  in  Charite.''  Patients  who  had 
used  for  disinfecting  purposes  external  applications  of  corrosive  subli- 
mate suffered  serious  derangement  of  the  intestines  from  which  they 
died.  The  real  cause  of  death  was  ascertained  only  after  making 
chemical  examinations  of  the  affected  organs,  which  revealed  the  pres- 
ence of  mercury,  and  this  could  only  be  traced  to  the  corrosive  subli- 
mate which  had  been  used  externally.  Since  the  foregoing,  Professor 
Virchow  observed  three  more  cases  of  fatal  poisoning  from  corrosive 
sublimate.— Ztg.,  1888,  page  13.
